This map provides information on speed limits that are posted on state-maintained roadways in Virginia. Cities and towns set their own speed limits and these are not available to show on the map. Zoom in on the map to display the speed limits. Speed limits exist for all roads however; where this information is not available for mapping, they are not displayed. Most roads where speed limits are not shown are either rural, secondary roads (routes numbered 600 or greater) where a statutory 55 mph speed limit typically applies, or subdivision streets where a statutory 25 mph speed limit usually applies. These statutory speed limits are often are not posted on these roads. Click on any roadway to display the speed limit information.

This map contains speed limits for all roads in the National Road Database (NWB).

Description from Rijkswaterstaat: "Since 2022, the features are Trees, Entrances, Bowl Boundaries, Parking Points , Parking spaces, Traffic center, Traffic types, Road width, Road categorization and Road narrowings added as a csv file to the database."

"The possible speeds that can be entered are 5, 15, 20, 30 40, 50, 60, 70, 80, 90, 100, 120, 130 km per hour, N/A and unknown. The speeds only apply to roads that are open to car traffic. On cycle paths , footpaths and other roads that are not open to car traffic, the speed is unknown. This also applies to the ferry connections. The file provides variable maximum speeds with a start time and an end time. These mainly apply to motorways. Outside this period with the indicated start time and end time, an alternative speed applies. So, for example, between 6:00 AM and 7:00 PM the speed limit is 100 km per hour and outside of that the maximum speed is 120 km per hour."

Traffic decisions, via the Knowledge and Operation Center for Official Government Publications (KOOP), are used to detect and process changes in speed limits.

Disclaimer:

A number of roads are currently still listed as "unknown" while the speed limit does not actually apply here (pedestrian paths and cycle paths, for example).

The road characteristics database (WKD) for speeds contains speed limits for all roads in the NWB. At the beginning of 2017, WKD was filled for the entire Netherlands with data supplied by municipalities. From that moment on, the new traffic decisions have been used via the Knowledge and Operation Center for Official Government Publications (KOOP) to detect and process changes in speed limits. The NWB changes faster than the speed limits are supplied by the road authorities or placed in COOP. Algorithms are used to supplement the speed where necessary on short intermediate road sections. As a result, the speed limit is unknown for a few percent. Since 2022, the features Trees, Entrances, Bowl Boundaries, Parking Points, Parking Spaces, Traffic Center, Traffic Types, Road Width, Road Categorization and Road Narrowings have been added to the database as a CSV file. NB: In residential areas where a maximum speed of 30 km per hour applies, or in a residential area, this leads to major deviations from reality. The number of rural roads with a 60 km limit has also increased significantly since 2017. The possible speeds that can be entered are 5, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 120, 130 km per hour and unknown. The speeds only apply to roads that are open to car traffic. On cycle paths, footpaths and other roads that are not open to car traffic, the speed is entered as unknown. This also applies to the ferry connections. The file provides variable maximum speeds with a start time and an end time. These apply in particular to motorways. Outside this period with the indicated start time and end time, an alternative speed applies. So, for example, between 6:00 AM and 7:00 PM the speed limit is 100 km per hour and outside of that time the maximum speed is 120 km per hour. The road characteristics database for speeds also contains the recommended speed limits that apply to a specific road section or part thereof.

This service provides lines representing posted speed limits along centerlines of North Carolina state-maintained roads. This data comes from traffic ordinances governing speed limit; where there is no ordinance, the speed limit is 35 within municipalities and 55 outside. The N.C. Department of Transportation sets the speed limit for all state-maintained roads, including access-controlled highways, which are highways with medians that require drivers to enter or exit only at interchanges with bridges, inside the town or city limits. For other state-maintained roads within the municipal limits, NCDOT and the town or city must concur before changing the speed limit. Roads are designed for a specific speed. NCDOT may review the speed limit for various reasons, such as part of a study to improve highway safety, or for proposed new developments. Citizens and local officials may also request NCDOT to conduct a speed zone study to determine whether a road has the appropriate speed limits and signage.The department considers several factors when adjusting the speed limit, such as:Alignment of the roadwayTypes of development along the roadwayThe density, or number, of driveways on a corridorHow far one can see the roadCrash historyVarious speed dataOne of the most common types of speed data NCDOT uses is based on the speed at or below which 85 percent of drivers are traveling. NCDOT uses the 85th percentile to help avoid posting speed limits that are artificially low, which can become difficult to enforce. In the absence of strict enforcement, most people drive at the speed they are comfortable with, regardless of the speed limit.MetadataThe metadata for the contained layer of the NCDOT Speed Limit Service is available through the following link:Speed LimitPoint of Contact North Carolina Department of Information Technology -Transportation, GIS UnitGIS Data and Services ConsultantContact information:gishelp@ncdot.govCentury Center – Building B1020 Birch Ridge DriveRaleigh, NC 27610Hours of service: 9:00am - 5:00pm Monday – FridayContact instructions: Please send an email with any issues, questions, or comments regarding the Speed Limit data.

This layer shows the New Zealand Road network with along with the current speed limit applied to the road. This data is generated nightly from the National Speed Limit Register. Please note, some roads have variable, seasonal or emergency speed limits applied. For further detail about a road segment, click the segment in the map to view the full details of the segement.

Here are a few use cases for this project:

1. Traffic Management Applications: Traffic authorities can use the "Speed Limitation" model to monitor highways and city roads for compliance with speed limits. If a vehicle is detected to be exceeding the speed limit, automatic notifications can be sent either to the vehicle's dashboard (in smart cars) or directly to traffic police.

2. Navigation And Map Services: Integrate it into map services like Google Maps, Waze, or in-car navigation systems to alert drivers about the speed limits in real-time, improving road safety and preventing speeding tickets.

3. Autonomous Vehicle Systems: Utilize this model as part of the guidance and regulation systems in self-driving cars. The cars will constantly scan for these signs to adapt their driving speed in real-time, ensuring they adhere to road regulations.

4. Traffic-Related Intelligent Tutoring Systems: Educators can leverage it in driving schools or online driver education programs, teaching new drivers to identify and understand the diverse speed-related traffic signs and abide by them.

5. Research and Studies: Researchers in traffic engineering and road safety can use this model to investigate the impact of different speed limits on traffic flow and accident rates, strengthening their understanding of real-world traffic conditions and proposing efficient road management strategies.

This dynamic map service provodes a a linear representation of speed limit changes based on signs in the field or speed zones established by an Official Order.

Legal Speed Limit (State and Local Roads)The maximum speed limit allowed under the provisions of the State Traffic Act and Regulations. Road speed limits are used to regulate the speed of road vehicles. Speed limits may define maximum (which may be variable), minimum or no speed limit and are normally indicated using a traffic sign. Speed limits are set by the Commissioner of Main Roads Western Australia (Regulation 297 of the Road Traffic Code 2000) and enforced by national or regional police and/or judicial bodies.This layer shows the location of legal speed limits on all public access roads found in the Integrated Road Information System (IRIS) and is provided for information only.Note that you are accessing this data pursuant to a Creative Commons (Attribution) Licence which has a disclaimer of warranties and limitation of liability.
